Abstract
A production trial was carried out on 100 male growing raccoon dogs to study the effects of low protein diets with Lysine (Lys) and DL-Methionine (Met) supplementation on growth performance and N-balance. The treatment codes were P30, P27, P24, P21 and P18. The protein contents [g kg-1 DM (dry matter)] of the diets were 295, 268, 237, 202 and 175, respectively. Lysine and DL-methionine were added to P27, P24, P21 and P18 to yield a total dietary content of Met and Lys corresponding to that in P30. From July to mid-September, Average Daily Feed Intake (ADFI), Average Daily Gain (ADG), Nitrogen (N) intake, Faecal Nitrogen (FN), Urinary Nitrogen (UN) and N retention were significantly reduced with dietary protein level decreasd (p<0.05), no significant differences among P30, P27 and P24 (p>0.05). In conclusion, when the dietary protein decreased to 24% with Met and Lys supplementation for raccoon dogs would be beneficial in terms of reduced feed expenses and lower nitrogen emissions to the environment.
